Edward Robertson (b.1809)
Edward entered the Royal Academy Schools in 1827 and he exhibited his miniatures at the Royal Academy from 1830 to 1837. He is recorded as residing in Dublin from 1831 to 1832 and had previously exhibited his work at the Royal Hibernian Academy in 1826.
Edward Robertson was the son of the eminent Scottish miniaturist Andrew Robertson (1777-1845) by his first wife Jenny. It can be presumed that Edward was initially trained as an artist by his father, who was one of the leading portrait miniaturists in London during the first four decades of the nineteenth century...
A portrait painted five years after the present example, of Edward’s brother, Captain Charles Robertson, is in the collection of the National Galleries Scotland [PG 2949]. Charles Robertson was present at the signing of the Maori Treaty at Russell in 1840 and conveyed the document to Governor Phillip in Sydney (hence Cape Robertson, New Zealand, is named after him).  Both extant portraits by Edward Robertson demonstrate a confidence in the fluid handling of watercolour, akin to the technique of an oil painter, that distinguished their father’s career so profoundly.
 The Treaty of Waitangi was an agreement made in 1840 between representatives of the British Crown and more than 500 Māori chiefs. It resulted in the declaration of British sovereignty over New Zealand by Lieutenant Governor William Hobson in May 1840.
